Birth Control Methods01:22

Birth Control Methods

7.1K
Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Intrauterine Drug Delivery Systems01:21

Intrauterine Drug Delivery Systems

100
Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...

Drug Delivery: Enteral Route01:18

Drug Delivery: Enteral Route

2.3K
The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

Ovarian Cycle01:27

Ovarian Cycle

5.0K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Infertility in Females01:28

Infertility in Females

5.0K
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.

Meiosis II01:57

Meiosis II

209.9K
Meiosis II is the second and final stage of meiosis. It relies on the haploid cells produced during meiosis I, each of which contain only 23 chromosomes—one from each homologous initial pair. Importantly, each chromosome in these cells is composed of two joined copies, and when these cells enter meiosis II, the goal is to separate such sister chromatids using the same microtubule-based network employed in other division processes. The result of meiosis II is two haploid cells, each...

Summary
This summary is machine-generated.

Emergency contraception is crucial for preventing pregnancy. While options like emergency contraceptive pills and copper IUDs are effective, their use is limited by knowledge gaps and access barriers, particularly for obese women.

Area of Science:

  • Reproductive Health
  • Pharmacology
  • Contraception

Background:

  • Emergency contraception (EC) is vital for preventing unintended pregnancies.
  • Access to and options for EC have evolved.
  • Knowledge gaps persist among patients and providers.

Purpose of the Study:

  • To review current understanding and utilization of emergency contraception.
  • To highlight changes in EC access and available methods.
  • To address the effectiveness and safety of EC options.

Main Methods:

  • Review of recent literature on emergency contraception.
  • Analysis of hormonal EC pill efficacy in different BMI groups.
  • Evaluation of copper intrauterine device (IUD) as EC.
  • Assessment of knowledge and access barriers.

Main Results:

  • Emergency contraceptive pills may be less effective in obese women.
  • Levonorgestrel (LNG) dosage adjustments are being studied for obese women.
  • Copper IUD is the most effective EC method.
  • Repeated use of LNG and ulipristal acetate (UPA) is safe.
  • Starting hormonal contraception post-LNG is immediate; post-UPA requires a 5-day delay.
  • Knowledge deficits and access issues hinder EC use.

Conclusions:

  • Emergency contraception is an underutilized but important pregnancy prevention tool.
  • Current EC methods, including copper IUD and pills, are safe and effective.
  • Addressing knowledge gaps and improving access are critical for wider EC utilization.
